Where are magnetic strips used?
Magnetic strips are commonly used on the backs of credit cards. They are also on other, similar items, such as some states' driver's licenses, identification cards, and store loyalty cards.
The magnetic strips on the back of bank cards and credit cards can be affected by strong magnetic fields or being close to weak magnetic fields. When you keep credits cards in a wallet with magnetic strip touching or being very close together, it is possible for the magnetic strips to affect each making them unreadable. Even so, the credit cards can still be used by manually keying in the credit card number.
The earth maintains a magnetic field due to the metals that make up its core. Thus, all rocks are influenced by this magnetic field and "face" the direction the field is "facing". Every few hundred million years the poles switch, and with it the magnetic field. Similarly, all rocks "face" the new direction. Magnetic strips are indicators of when the magnetic field of the Earth changed.
A magnetic strip reader does exactly what it says: it reads the magnetic strip on the card that the strip is attached to. The most common cards with magnetic strips are of course debit and credit cards, but the usage of magnetic strip readers is much wider. A number of ticket solutions, for instance for parking, coffee machines or toll roads also use magnetic strips. The information that is read by the reader depends very…
Burmah Castrol Strips are used to verify the prescence, direction and to a degree the force of a magnetic field. They are used in determining the effectiveness of a Magnetic Particle Inspection (MPI) procedure when inspecting steel pipes and structures. When in the correct orientation the BC strip will show indications across the strip when it is used with either wet or dry mag particle inspection media.
Magnetic data can be connected to separate mediums. In digital media, it equates to the system of storing information on magnetic tape via digital recording. It can also indicate the storage of data on a magnetized medium such as a computer hard drive. Some examples of magnetic storage data are magnetic strips on credit cards, floppy disks and recording tape.
Magma contains many materials which are magnetically affected. When this magma is ejected from the mantle and begins forming new crust, these materials align to the earth's magnetic field. The crust hardens, and the magnetic alignment is fixed (just as in normal magnets, made by using a similar process). The magnetic fields are 'visile' in strips of material, hence the term 'magnetic striping'. seafloor spreading
Magnetic particles suspended in liquid magma align themselves with the Earth's field, and when the magma solidifies they retain that alignment even after the direction of the Earth's field changes. So, for instance, as magma spreads outward from the Mid Atlantic ridge, you get a series of magnetic strips of varying alignment as you move outward, and the strips on the west side correspond with those on the east side.
I'm assuming you are referring to the magnetic strips designed to be attached to a wall. - One advantage is having your knives visible and easily accessible. - Another is that they can be stored above the reach of any small children who might be running through the kitchen, or playing in cabinets and drawers. - Moreover, magnetic holders keep your knives out of drawers where they can be dulled by shifting against other utensils…
